To summarize my responses to what you had originally posted:

"True" Epyc has always had a differentiation from the consumer line in the scaling+features, Ryzen PRO has always had a differentiation from the consumer line in the features, and "fake" Epyc 4000 has always had differentiation from the consumer line in the same way as PRO had/has.

Of all of the combinations, only the newer Epyc 4000 line compared with the pre-existing Ryzen PRO line have actually lacked differentiation from each other and this change in encryption support on the consumer line does not help with that.
